Pedders PED-160024 eXtreme XA Coilover Kit for 2008-2014 Subaru WRX Monotube

Vehicle Fitment

• 2008-2014 Subaru Impreza WRX (GH / GJ chassis, EJ257 2.5L H4 Turbo, AWD) - models with 26mm wide clevis bracket on front strut
• 2008-2014 Subaru Impreza WRX Limited (GH / GJ chassis, AWD) - models with 26mm wide clevis bracket on front strut
• 2009-2014 Subaru Impreza WRX Premium (GH / GJ chassis, AWD) - models with 26mm wide clevis bracket on front strut
• 2010-2014 Subaru Impreza WRX - STi optioned WRX trim with 26mm wide clevis bracket (NOT the standalone STi model)
• 2008-2014 Subaru Impreza (non-WRX base, Premium, Sport, Sport Limited, Sport Premium, Limited, Outback Sport) - all trims using the same GH / GJ front strut with 26mm clevis bracket

Fitment Notes

• Fits models equipped with a 26mm wide clevis bracket on the front strut - this is the critical fitment measurement that must be verified before purchase
• Does NOT fit standalone Subaru WRX STi models equipped with a 30mm wide clevis bracket on the front strut - a different Pedders kit is required for the STi
• The "STi optioned WRX" trim (WRX with STi appearance package) uses the WRX's 26mm front strut and IS compatible - the standalone WRX STi model uses a 30mm front strut and is NOT compatible
• Ride height adjustment is independent of spring preload - ride height can be raised or lowered without disturbing the spring preload or lower spring seat position
• Warranty: 24 months / 24,000 miles, applies to original purchaser retaining ownership of the vehicle on which the parts were originally installed

Features

• 30-position adjustable damping - a single click changes the compression and rebound damping setting simultaneously, providing a precise and repeatable tuning range from daily-comfort to track-aggressive without separate adjustment tools
• Fully threaded monotube damper body - allows independent ride height adjustment across the full height range without changing the spring preload or lower spring seat, maintaining consistent spring behavior at any ride height setting
• Gas pressurized monotube damper design - eliminates the oil aeration associated with twin-tube shocks, delivering consistent, fade-free damping force throughout the suspension travel and during extended track use
• Alloy steel motorsport coil springs individually rated and tuned for the Subaru WRX / Impreza application - 6 kg/mm front and 8 kg/mm rear, providing a progressive and balanced spring platform for both street and track driving
• Factory-style bracketry - engineered mounting brackets that interface directly with the OEM chassis pickup points without modification, maintaining factory geometry and alignment correction points
• Independently tuned for each corner - Pedders develops the spring and damper specification for each specific vehicle application rather than adapting a universal setup
• Suitable for both street tuners and weekend track day drivers - the eXtreme XA is Pedders' performance coilover line designed to deliver track capability while remaining drivable on public roads
• 24-month / 24,000-mile warranty from Pedders USA - backed by Pedders' commitment to quality and engineered suspension development

Product Description

The Pedders PED-160024 eXtreme XA Adjustable Coilover Kit is a complete 4-corner coilover suspension system engineered specifically for the 2008-2014 Subaru Impreza WRX and non-WRX Impreza models equipped with the standard 26mm wide clevis front strut bracket. Developed by Pedders - a suspension company with roots in the Australian motorsport market since 1950 and a US presence since 2006 - the eXtreme XA line represents Pedders' application-specific approach to performance coilover design: each spring rate, damper valving, and mounting bracket geometry is developed and validated for the individual chassis rather than adapted from a generic platform.

The system uses fully threaded monotube damper bodies front and rear, allowing the ride height to be raised or lowered independently of the spring preload and lower spring seat position. This is a critical design advantage over non-threaded or shock-body-mount systems - the driver can change ride height without altering spring behavior or re-setting the spring preload, making fine-tuning far more precise and repeatable. Each damper features 30 positions of adjustable damping, with a single click changing both compression and rebound simultaneously to quickly move between a comfortable road setting and a firmer track-oriented setup. The gas pressurized monotube design eliminates oil aeration that degrades damping consistency in twin-tube alternatives, ensuring fade-free performance during sustained high-load driving at the track.

The alloy steel motorsport coil springs are individually tuned to the WRX / Impreza application at 6 kg/mm front and 8 kg/mm rear - a rear-biased spring rate pairing that supports the AWD platform's weight distribution and promotes balanced handling characteristics across a wide variety of driving conditions. Critical for WRX buyers: this kit fits only models with the **26mm wide clevis bracket** on the front strut. The standalone Subaru WRX STi uses a wider **30mm clevis bracket** and requires a separate Pedders kit - verify the front strut clevis width before ordering. The STi optioned WRX (appearance package) uses the WRX's 26mm strut and is compatible. The kit carries a 24-month / 24,000-mile warranty from Pedders USA.
